case insensitivity in multi-protocol environment (cifs/nfs)

I'm looking for a bit of information. I'd like to understand how netapp renames/presets files of conflicting case to CIFS. Below I have 3 files and when accessed via cifs those filenames are changed to DOS 8.3 format.

What option actually accomplishes this? Is there a way to prevent it, or change the behavior? More importantly... is there any way to get CIFS to behave in such a way that a cifs client COULD access longerfilename.txt and longerFILENAME.txt natively?

When this option is on, CIFS will preserve the case when files are created or renamed. If this option is turned off, all filenames will be forced to lower case. This can help with compatibility between certain 16-bit applications and UNIX tools."

now as far as long file name support that is more of a function of the client OS I think. If files are created / read / renamed in a 16 bit app then they will get the 8.3 short name. There is no limitation in ONTAP there.
